Linux centos6.6 under vmware virtual machine only has lo, no eth0 network card, random allocation of ip address, fixed ip address, etc.

This problem stuck me for more than a day, and the questions I found on Baidu were various, but it confused me. Finally, the practice was successful, and the configuration process was recorded.

Configure network card and randomly assign ip address

I installed the basic server version, using NAT mode

 

Then, make sure that in the service, these two are started

 

 

When centos was just installed, there was no eth0 network card.

cd /etc/sysconfig/network-scripts

Then ls, you can see that ifcfg-eth0 exists, but it is not activated

vi ifcfg-eth0

It can be seen as follows

 

 Pressing the "insert" key means entering edit mode. Set ONBOOT=yes, then press "esc" key, ":" key, "w" key, "q" key, ifcfg-eth0 is modified

service network restart

Then ifconfig, you can see that eth0 has been randomly assigned an ip address

Ping baidu.com, you can see that you can connect to the Internet (ctrl+c to exit ping)

 At this time, remote tools such as putty and winscp can also be connected.

 

fixed ip address

 Virtual Machine-->Edit-->Virtual Network Editor-->vmnet8-->nat Settings

On this page, you can see that the gateway IP is "192.168.255.2" (different for each machine)

Close the gateway viewing page and click the "DHCP Settings" button at the bottom of the page

You can view network information, including:

The starting IP address is "192.168.255.128"

The ending IP address is "192.168.255.254"

The subnet mask is "255.255.255.0"

 

Check the status of "VMware Network Adapter VMnet8" in Network and Sharing Center

 

192.168.255.1 is the address assigned by the virtual router to Windows

192.168.255.2 is the gateway address of the virtual router

Then, in centos, enter the command "vi /etc/sysconfig/network-script/ifcfg-eth0" to modify the eth0 information, and press the "insert" key to modify

Modify information:

ONBOOT=yes

BOOTPROTO=static

add information:

IPADDR=192.168.255.100 (adjusted according to the gateway)

NETMASK=255.255.255.0

GATEWAY=192.168.255.2

After modification, press "esc key", ":" key, "w" key, "q" key

service network restart

If the error *** is already in use for device eth0 appears, add ARPCHECK=no to the ifcfg-eth0 file just now

 

 Check the ip you just configured

 

 Can the speed test be connected to the Internet?

 

you're done
